Sue is very nice and she showed us around the apartment! How to get to the city and help getting a cab etc.
Room is very clean, huge and we had very comfortable stay.
There were some some points that we would like to share with next travelers.
1) The location is not very central Bangkok but 5-7mins walk to BTS station, if you would like to enjoy night life in Bangkok, this apartment location might not be the best but we had all we need around this apartment including some cafes, 24 hrs supermarket downstairs, and also lots of street food choices.
2) The condo security is not welcoming short stay guest, so they look at us with very suspicious look and the note in the lift says "Dear short term traveler and 'Friend's of' .... This is not a hotel..." I understand that where this is coming from and Sue explained that all condos in Bangkok changed the security system.

Just something I thought it would be helpful to share.
